Experiencing a “mismatch” headache is something many users have had to cope with when looking at your GST tables, and seeing a row highlighted in red. A row highlighted in red means that: “The tax credit you claimed is greater than what your suppliers have reported.”
In GST’s early days, you could claim credit depending on your own invoices. Things become more restrictive in 2026. If it’s not included in your GSTR-2B/2A, you can’t claim it.
At Bharatiya Tax Pro, we “clean up” these mismatches. Here’s an expert guide on identifying and resolving discrepancies without a tax liability.
1. Knowing Both Sides of the Coin
- GSTR-2A (The Supplier’s Record): This is always an up-to-date auto-generated report. Whenever your vendor submits their sale report (GSTR-1), it is reflected here. This is also the record the tax authorities have of the payments you made.
- GSTR-3B (Your Claim): This is your monthly return, where you declare how much Input Tax Credit (ITC) you have claimed.
When there is more GSTR-3B apart from GSTR-2A or GSTR-2B, the system considers that there is a shortfall in tax.
2. The Possible Reasons Behind This Scenario
Understanding the nature of the problem is essential before attempting to resolve any type of discrepancy. In our four decades of service in Bangalore, we have encountered three such instances of issues:
- The “Procrastinator” Supplier: Your supplier is late in filing their GSTR-1.
- Data Entry Errors: The supplier input the GSTIN for your company incorrectly, or the tax amount was input incorrectly.
- Classification Error: The supplier classified a B2B transaction as B2C (Business-to-Consumer), which keeps it off your 2A report.
3. The 4-Stage Process to Obtain a Resolution
Step 1: The Monthly Reconciliation
Step closings are for amateurs. Every single month, download your GSTR-2B and reconcile it with your purchase register, invoice by invoice. They are tools like Excel (VLOOKUP) or other invoice reconciliation software to help you identify missing invoices.
Step 2: Communication with Your Vendors
After you have identified the “Missing Invoices,” formalize the request with your vendors.
“Dear Vendor, Invoice #123 is missing from our GSTR-2A for October. Please add it to your GSTR-1 filing so we can claim our tax credit.” At Bharatiya Tax Pro, we manage this “Vendor Follow-up” on behalf of our clients so that the credit doesn’t disappear.
Step 3: Use Invoice Management System (IMS)
Starting late 2025/early 2026, the GST portal’s IMS lets you “Accept”, “Reject”, or “Keep Pending” invoices. If an invoice amount is incorrect, reject. This forces the supplier to fix it before the credit is locked.
Step 4: Adjust in Next Return
If you overclaimed credit in a previous month because of a mismatch, don’t be alarmed. You can “Reverse” that credit in the current GSTR-3B. On the flip side, if a supplier ends up filing a late invoice, you can “Reclaim” that credit now.
4. Risks of Not Dealing with Mismatches
If the discrepancy exceeds a certain threshold, the department generates an automated notice in Form DRC-01C. If you fail to respond to it or pay the difference within 7 days:
- Your next GSTR-1 might get blocked.
- You could get hit with 18% interest on the excess credit claimed.
- Your “Compliance Rating” will decline, making it harder to get refunds.
